I agree with you about the present... I didn't read any more into it. I'm shocked to hear that anyone did. If that had been the case... I think more precaution may have been made... locking the door and such.

I also think Lupin was hilarious every time he showed up somewhere with that whole spiel of his.

As to the character in question, I just don't really see why he's more significant than any other. Yeah it sucks that he's a (SPOILER)twin, but it equally sucks that (SPOILER)Remus and Tonks have a new child that will never meet them. In the end, it is all subjective so I suppose it doesn't matter. I guess I just see it differently. But that's the glory of book and sharing opinions they evoke in us.
